So, i downloaded the latest lightstreamer server and updated to latest client js libraries, but i am not permitted to use dashes. I use UUID to generate unique session id's for which my users are subscribing and it uses dashes.

Also i keep getting this annoying error about firefox, despite of i set:

engine.context.setDebugAlertsOnClientError(false);
and
page.context.setDebugAlertsOnClientError(false);
